MINING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 358,488, dated January 25, 1887.

Application filed April 12, 1886. Serial No. 198,533.

To all whom it may concern:

Be it known that 1, M. FRANK MONELLY, a citizen of the United States, residing at Sterling, in the county of \Vhiteside and Stateof Illinois, have invented certain new and useful Improvements in Rock and Goal Drills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawmarked thereon, which form a part of this specification.

My invention has reference to rock or coal drills, and pertains more especiallyto certain mechanism, hereinafter-described, more particularly adapted to drilling for blasts in coalmines and like situations where the room for working machinery is limited, and where the drilling is required to be done at various altitudes and in various directions.

In the drawings, Figure 1 is a side elevation. Fig. 2 is a section in line 90 ref Fig. 1. Figs. 3, 4., and 5 are detail views. Fig. 6 is a top View of the nut which holds the auger. Figs. 7 and 8 are partial plan views of the auger and its connections. Fig. 9 is an elevation. Fig. 10 is a section in'line y y of Fig. 7. Fig. 11 is a plan of my attachment for driving the auger. Fig. 12 is a cross-section in the line 2 z of Fig. 11. Fig. 13 is a detail cross-section on the line zz in Fig. 11, showing the feather K in position.

A A are parallel vertical tubes suitably united at their lower ends to a common central pivotal base, A and open at their upper ends.

B B are parallel round rods or bars united at their upper ends into a pivotal central point, B, and adapted to have their lower ends enter and be adj ust-able within the tubes A A. Set-screws O O, seated in the respective walls of the tubes A A, and having their compress, ing end in contact with the exterior of the bars B, serve as means of such adjustment.

D is a crossbar having the round central vertical hole D, and vertical end sockets, D through which latter are placed the tubes A, respectively. The cross-bar D constitutes the seat for the auger, and is adjustable to different altitudes by shifting vertically on the (N0 model.)

tubes A, being held at any desired height by set-screws D seated in the walls of the sockets D", and adapted to be screwed against the outer walls of such tubes.

E is a shearswivel consisting of two upwardly-extending jaws, E, mutually hinged at their lower ends and rounded into the stem E which latter is seated pivotally in and con forms to the central hole, D, in the cross-bar D.

The stem E has an annular recess, 15*, eu-' gaged by a horizontal set-screw, E which holds such stem from withdrawal but permits its lateral rotation in the hole or socket D.

F is the seat of the auger G, and consists of an open nut having lateral trunnions F,which threads in the nut F, and in its rotation is thereby advanced.

At the upper ends of the rods A is centrally seated the vertical stationary nut A, in which is seated a threaded bar, H, having lateral handles, and adapted to be screwed up against the roof, so as to hold the machinein position. A crank, J, is attached to the outer end of the shank of the auger G as a means of rotating the latter; but as it often happens that ablast is required at a point or in such direction that it is impracticable to operate the auger at the end for lack of crank-room, I obviate this difficulty by the provision of the foll0wing-described side attachment.

K is aframe in which are journaled at right angles to each other the engaging small bevelpinion K and large bevel-pinion K. The axle K of the latter is hollow, and is adapted to slip loosely on the auger G.

At one end of the frame K is formed the equal-sided socket K", which is passed over an equal-sided projection, F, on the outer end of the nut or auger-seat F, and fastened therein by the setscrew K. The outer end of the axle K of the small drive-pinionsK is fitted to receive the crank J. A feather, K, on the innerwall of the axle K of the larger pinion,

engages a longitudinal groove, G, in the shank .l" of thii auger G, and thereby the rotation of the axle K is communicated to the auger G, the feather K traversing the groove G and permitting the progress of the auger G. The auger-bit G is attached to its shank G by means of a U-shaped socket, G, in the latter, the inner end of the bit being shaped to enter and conform. to such socket, whereby oscillation in any direction is prevented.

The advantages of my invention are as follows: The side driving mechanism described is not only applicable in diagonal drilling, where the outer end of the auger-shank is too near the sides, floor, or root'to permit the crank to be used in the end of the auger-shank and the power increased by such side mechanism, but the socket K" and projection F being square and equalsided, the auxiliary driving mechanism can be attached above, below, or on either side of the auger G, as may be necessary or n'eferable. The threads within the nut- F extend also throughout the projection 1 and thus increase the strength of the nut and prevent the breaking of the threads on the nut or the auger. The projection F is in two parts, each of which is integral with the halves of the nut F, and the socket K also holds the said nut together in case of the casual withdrawal of the pin F. A further advantage is in having three pivotal hearings, to wit, the extremities ofthe machine, the central vertical socket, D, of the bar D, and the trunnions F of the nut F, whereby the tubes A A may be set nearly in line with the hole to be drilled and the auger projected obliquely between them in such line, and the boring there fore he done close to the side of the drift. The machine may be set at any angle. By adjusting the bars B within the tubes A a compact and simple mode is provided for length ening or shortening the machine without the inconvenience of extra pieces.

Vhat I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. The combination of the tubes A A, plo vided with common central base, A*, the bars B B, inserted, respectively, in said tubes, the set-screws C O, seated, respectively, in the walls of the tubes A and adapted to press against the bars B, so as to hold the latter adjustably within said tubes, the stationary nut A, the threaded bar H, seated in nut A, the cross-bar D, provided with central hole, D, and end sockets or holes, D", through which latter are respectively passed the tubes A,setscrews D seated in the walls of the sockets D and adapted to be screwed against the ex' terior of said tubes, the swivel E, provided with jaws E and stem E, and adapted tobe seated pivotally in the hole D, the inwardlythreadcd open nut F, provided with lateral trunnions F, pi votally seated, respcctively,in the holes E of the jaws E, and the auger G, seated pivotally in the nut F, whereby said auger can be shifted laterally, vertically, or obliquely, substantially as shown, and for the purpose described.

2. The combination, of the augur-seat F, provided with the angular projections F, the auxiliary frame K, provided with socket K, adapted to be seated on projections F, the bevcl-pinionK, the axle K of pinion K, jour naled in frame K, crank J, attached to axle K, pinion K", engaged and driven by pinion K, axle K of pinion K", adapted to slip on shank G of anger G, and provided with internal feather, K, to engage the groove G of shank G and the auger G, provided with shank G and groove J therein, substantial ly as shown, and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

M. FRANK MONELLY.
